Detailed Description

template<typename TImage>
class DGtal::DefaultImageRange< TImage >

Aim: model of CConstBidirectionalRangeFromPoint and CBidirectionalRangeWithWritableIteratorFromPoint that adapts the domain of an image in order to iterate over the values associated to its domain points (in a read-only as well as a write-only manner).

Template Parameters

TImage a model of CImage mapping points to values

NB: the underlying image is stored as an aliasing pointer in order to avoid copies. As a consequence the pointed object must exist and must not be deleted during the use of any instance of this class.

TODO: inherits from DefaultConstImageRange
